Germany opened its last new coal plant 3 years ago. In theory the last one, but soon the government will change and this likeley as well. And our eastern neighbors poland and co. certainly won't give up on coal anytime soon. So much for rich countries.

And china which is on average still poor, indeed invested more in coal than I was aware. But a coal tax specially for china seems rather geopolitical motivated to me.
